Add fzf key bindings function file with support for: - File search widget (Ctrl+T) - Command history search (Ctrl+R) (replaced by custom implementation) - Directory navigation (Alt+C) (replaced by custom implementation) Bindings work in both normal and insert modes, providing fuzzy search capabilities for fish shell navigation and command history.
